  • Make and document key architectural decisions, balancing innovation, risk, and regulatory requirements.
  • Break ambiguous, org-level problems into workstreams and delegate effectively to senior and junior engineers.
  • Partner with product and leadership to influence roadmap and prioritization with technical insight.
  • Proactively seek development opportunities and share knowledge with peers and junior engineers.

  • Deep expertise in microservices, event-driven architecture (Kafka), and RESTful and WebSocket API design
  • Strong knowledge of SQL and NoSQL data modeling and performance tuning
  • Extensive experience with AWS or equivalent, Docker and Kubernetes, and CI/CD at scale
  • Experience with observability and incident management for production systems
  • Experience in trading, exchange, fintech, or other high-throughput transactional systems is strongly preferred
  • Demonstrated cross-team leadership and the ability to explain complex tradeoffs to technical and non-technical audiences
  • Strong communicator, able to explain complex technical concepts to both technical and non-technical audiences
  • Proactive, growth-focused, and highly adaptable with a strong sense of ownership
